You can choose a Chinese name! Having a proper Chinese name is nice! I recommend you choose a surname based on your actual surname, and then ask a Chinese friend to help you choose another one or two characters. You can choose them on sound, how they look, or even meaning! Laurence

It is a bit of challenge for some Chinese to pronounce. People normally do not remember those name which they have difficulty to remember. Name in China normally comes in 2 parts. The family name comes first，then followed by your name with one or two words. In my opinion, "阿娅" or “娜娅” will be a nice choice. They both sound exotic in Chinese. For “娜娅”, some of us do give a similar name to a new born female member. "阿娅" will be a name informal. We often call a friend like “阿……”. It is a name people remember. The family name in China normally only have a word, there are exceptions, you can extract a word from your family name. Of course, the method Laurence also proposed a good approach. In this case, you need search for a common Chinese family name，and a couple of meaningful words for your first name. Good luck. - Yi

Nastya in Chinese could be 纳斯塔雅。But it's not that easy to pronounce. Maybe you could choose a one-word surname and a two-word first name. That would be the most common pattern of a Chinese name.

Настя ？娜斯佳----Это правильно.

The pronunciation of Настя is 茄茶　to the Japanese Chinese(kanji） . The meaning is eggplant tea. The Japanese notation of Nastya is ナスティア. For your reference.
